PurposeTo assess magnetic resonance imaging (MRI) features after prostatic artery embolization (PAE) for the treatment of medium- and large-volume benign prostatic hyperplasia and to correlate prostate volume with clinical indexes.MethodsWe retrospectively evaluated 28 patients who underwent PAE. MRI examinations of the prostate were performed to evaluate signal intensity changes and the characteristics of infarcted areas. Prostate volume and the apparent diffusion coefficient (ADC) were measured at an average of 10 days post-PAE and at 1, 3, 6, and 12 months post-PAE. Some clinical indexes were evaluated before and 12 months after PAE. The pairedttest, ANOVA, and multiple linear correlation analyses were performed by using the statistical software, SPSS.ResultsAll patients experienced prostatic infarction. The prostate volume decreased continuously (p< 0.05). The ADC values before and after 1, 3, 6, or 12 months of embolization (b= 1000 and 2000 s/mm2) were statistically significantly different. The ADC values (b= 3000 s/mm2) were also statistically significantly different before and at each interval time after embolization (p< 0.05). Prostate volume changes correlated significantly with patient age and post-void residual urine volume (p< 0.05).ConclusionsMRI can be used for assessing changes in signal intensity and ADC values of infarction as well as the volume of the prostate after PAE. After PAE, ultrahighbvalue diffusion-weighted imaging (DWI) can show early infarction better than lowerbvalue DWI.
